Hep-Ex explores the fascinating intersection where particle physics meets experimental reality. This field investigates how scientists build massive detectors and accelerate particles to test the fundamental laws of nature, turning abstract theories into measurable data. It is the rigorous process of searching for new particles or forces that could reshape our understanding of the universe, often requiring years of collaboration and engineering.
At Gist.Science, we ensure these discoveries become accessible to everyone. We process every new preprint in this category directly from arXiv, generating both plain-language explanations for curious readers and detailed technical summaries for specialists. Our goal is to bridge the gap between complex experimental results and public understanding without losing scientific nuance.
Below are the latest papers in Hep-Ex, freshly summarized and ready for you to explore.
This paper presents beam-test results demonstrating that pre-production Low Gain Avalanche Detectors for the ATLAS High Granularity Timing Detector meet all performance requirements, including charge collection, time resolution, and hit efficiency, even after neutron irradiation simulating end-of-life High Luminosity-LHC conditions.
This proceeding presents an overview of recent MicroBooNE results on neutrino-argon cross-section measurements across inclusive, CC0, and rare channels, utilizing advanced reconstruction tools to benchmark interaction models and constrain backgrounds for future liquid argon neutrino experiments like DUNE.
This paper proposes a protocol to achieve three-dimensional quantum squeezing of optically levitated nanospheres via frequency jumps, demonstrating that approximately 10 dB of squeezing is feasible with current technology to enable impulse detection beyond the standard quantum limit despite decoherence.
This paper presents the physics program and detector design of the Spin Physics Detector (SPD) project at the NICA collider, which aims to investigate the spin structure of protons and deuterons, particularly gluon distributions, through high-luminosity collisions of polarized beams.
This paper presents new results from the ATLAS detector at the LHC regarding searches for vector-like quarks and leptoquarks, which are hypothesized particles in extensions of the Standard Model designed to address the hierarchy problem and flavor anomalies.
This paper examines the growth and impact of the ATLAS Collaboration's Virtual Visits programme, which since 2010 has successfully bridged the gap between particle physics and the global public by providing live, interactive, and language-accessible tours of the ATLAS detector and control room.
This paper proposes a unified KSVZ-type axion model incorporating modular symmetry and a global symmetry to simultaneously explain the origin of radiative Dirac neutrino masses, the strong CP problem, and dark matter, while predicting a massless neutrino and testable signatures for charged lepton flavor violation and axion-photon coupling.
This paper employs a nonperturbative Hamiltonian framework using Daubechies wavelets in momentum space to analyze dimensional theory, successfully demonstrating the emergence of a strong-coupling phase transition in the sector.
This paper proposes a refined search strategy targeting a narrow axion mass window of 78.6 to 79.6 micro-eV (18.99–19.01 GHz) using a resonant cavity detection scheme based on the inverse Primakoff effect, supported by recent simulations and novel experimental designs involving Josephson Parametric Amplifiers and Resonant Tunneling Diodes.
This paper presents the threshold resummation of large logarithms up to NNLL accuracy for on-shell -boson pair production at the LHC, demonstrating that matching these resummed predictions to NNLO fixed-order results significantly reduces scale uncertainties and provides a precise description of the invariant mass distribution in the high-energy regime.
